## page was renamed from Electronics/Quadrant Photodetector Design

This page describes the design of a new quadrant photodetector.

The main applications are for DC beam sensing and optical lever servos. These are non-critical applications.

The DC beam sensing ones are mainly for beams on the PSL and IO optics. We should also add a QPD to each of the ISC readout paths.

  1. Application note attachment:AN_940.pdf on selection of low noise opamps.
